Existing Development The subject site on the north side of S. 144 Street is vacant of any buildings. 40 Ave. S. a short local access street runs north south through the site and ends in a cul -de -sac that provides access to parking for an apartment building that fronts on 42 Ave. S. The subject site on the south side of the S. 144 Street contains a vacant commercial building, a separate small building that is used as a barber shop, a utility storage yard, a basketball court and accessory parking for the King County Housing Authority. Surrounding Land Use Within the north block, in the southeast corner is the existing 5,200 square foot Foster Library. The current proposal does not include any redevelopment of the existing library building. In the immediate vicinity are a number of public uses such as the high and middle schools, public pool, and a neighborhood park; a church and mosque; neighborhood retail such as drug stores, grocery store, laundromats, and dry cleaners; and a variety of food establishments. There are numerous residential uses in the area from motels, apartments to single family homes. Staff Report L13 -031 Page 2 of 12 98 Proiect Description Tukwila Village is a 6.4 acre project that will straddle a two lane collector arterial and will be developed in three phases. The City of Tukwila, the property owner, entered into a Disposition and Development Agreement (DDA) giving Tukwila Village Development Associates the right to develop the property according to an approved conceptual plan. The City also approved a Development Agreement that waived certain Code requirements. Shared parking was approved as part of those Agreements. The concept of shared parking is that separate parcels of land (and therefore potential ownership) and the uses and buildings on those parcels, may share parking stalls. Shared parking allows for parking on one parcel to be used by the businesses located on a separate parcel or to allow for demand for the stalls to vary during the time of day or the seasons of the year. Within the DDA, under section 2.4 "D. Additional Approvals - The City shall have the right to require and approve easements for utilities vehicular access pedestrian access shared parking and shared maintenance for each Development Phase to ensure that the entire Development functions as an Integrated whole even if the Development Parcels and/or Development Phases come under Separate ownership and management. " Approval for shared parking is therefore not required by this decision. Attachment A shows the three phases of development. The entire project contains: • Four residential and commercial buildings with a total of 403 housing units (80 market rate apartments, 4 live /work apartments, 319 senior units;) 30,000 square feet of commercial/office space; and a 2,000 square foot community policing station. • A new 10,000 square foot King County Library System neighborhood library. • A new 4,200 square foot community building and cafe adjacent to a half acre outdoor plaza. • A total of 450 on -site structured and surface parking stalls. The site plan (Attachment B) shows parking location and totals per Phase as well as the overall site layout for buildings, driveways, and sidewalks. Phase 1 contains: Building A, which is a seven story structure, includes: • two levels of structured parking of 85 parking stalls on two separate levels and with restricted access, • approximately 8,200 gross rentable square feet of commercial/retail space and four live - work studio loft dwelling units on street level; and • five levels of 80 residential dwelling units containing a mix of studio, one - bedroom and two - bedroom apartments, and • 53 surface parking stalls and one loading stall for the library's use. Staff Report L13 -031 Page 3 of 12 99 Building C, which is an approximate 4,210 square foot, one story community building adjacent to a 32,000 square foot community plaza, consists of a wide variety of landscaped and hardscaped areas. The community building includes: • a large flex assembly space containing approximately 1,711 gross square feet, • a catering kitchen containing approximately 368 gross square feet of space, • storage space, reception space, men's & women's public restroom space, • a cafe / coffee shop containing approximately 1,268 gross square feet of retail space, including a seating area, kitchen area, refrigeration area and office area; and • an indoor /outdoor fireplace and outdoor seating area and 11 surface parking stalls. Tukwila Library is a new one story 10,000 gross square foot neighborhood branch of the King County Library System. The total number of parking stalls provided for Phase 1 on the surface and under Building "A" is 149 stalls. Phase 2 contains: Building D, which is approximately 134,960 square feet, includes: • One level of below grade structured parking containing 49 garage parking stalls • One level of approximately 13,000 square feet of rentable commercial office space; • Five levels of residential dwelling units for seniors (70 total units) containing a mix of one - bedroom and two - bedroom apartments; and • approximately 19 surface parking stalls for commercial office use. Building E, which is approximately 134,960 square feet, includes: • 103 structured parking stalls • approximately 1,150 gross rentable square feet of commercial/retail space, and approximately 2,000 gross rentable square feet of police resource center space, • four levels of residential dwelling units for seniors (125 total units) containing a mix of one - bedroom and two - bedroom apartments, semi- private outdoor landscaped courtyard; and • approximately 11 surface parking stalls for commercial/retail use. The total parking provided for Phase 2 on Parcel D and E is 182 stalls. Phase 3, located north of S. 144 Street and adjacent and on the eastern edge of Phase 1 Building B includes: • one level of structured parking containing 86 parking stalls for residential use only and 1,800 square feet of rentable commercial/retail space, Staff Report L13 -031 Page 4 of 12 100 • four levels of residential dwelling units for seniors (125 total units) containing a mix of one - bedroom and two - bedroom apartments, and • approximately 34 surface parking stalls for commercial/retail and flex use. Phase 3 parking calculation The total parking provided for Phase 3 on Parcel B is 120 stalls. II. Summary of Proposed Action 1. Parking Standard for a Use not Specified The required number of parking stalls for a Live/Work residential unit is not specified under the City's parking regulations. Under the "Uses Not Specified" section of the Off - Street Parking Chapter, (TMC 18.56.100) the Director shall determine the required number of parking stalls for uses that are not specified in the City's parking regulations. A Parking Standard Determination must be made following a Type 2 process as described in the Permit Application Types and Procedures Chapter (TMC 18.104.) The Director's Determination shall be based upon the requirements for the most comparable uses specified in the Off - Street Parking Chapter. The applicant has submitted a table showing the parking requirements by use, including the requested 1 stall per Live/Work unit. (Attachment C) 2. Complimentary Use The following definition of a complementary use is from the Tukwila Zoning Code: "A complementary use is a portion of the development that functions differently than the primary use but is designed to serve or enhance the primary land use without creating additional parking needs for the primary traffic generator. Up to 10% of the usable floor area of a building or facility may be occupied by a complementary use without providing parking spaces in addition to the number of spaces for the principal use. Examples of complementary uses include pharmacies in hospitals or medical offices, food courts or restaurants in a shopping center or retail establishments." (TMC 18.56.070 (D) Cooperative Parking Facility) For Tukwila Village the residential units are considered the primary use. The applicant is requesting that the City approve 10 % of the usable floor area from the non - residential uses be considered complementary uses and therefore not subject to the parking supply requirement. Staff Report L13 -031 Page 5 of 12 101 3. Shared Use The concept of complementary use is that a parking space can serve two or more individual land uses without conflict or encroachment and is possible because of two conditions: • Variation in the accumulation of vehicles by hour, by day or by season at the individual land use; and • Relationships among the land uses that result in visiting multiple land uses on the same auto trip. The concept of shared parking has similarities with complimentary parking but also is used to describe two or more parcels: • with no physical separation but connected with sidewalks allowing free pedestrian movement between buildings; and • collectively satisfy the parking requirement but individually one or more of the parcels are not able to meet the Code requirements. Applications for shared, covenant or complementary parking are allowed and must be processed as Type 2 decisions per the Cooperative Parking Facility Section of the Zoning Code. (TMC 18.56.070(E.) There are no specific decision criteria for complimentary and shared parking. III. Decision Authority The purpose of the Off - street Parking and Loading regulations chapter is to provide for adequate, convenient, and safe off -street parking areas for the different land uses described in the City's Zoning Code. (TMC 18.56.010 Purpose) At the time any building or structure is erected, enlarged or at the time there is a change in its principal use, off -street parking and loading spaces must be provided as an accessory use in all zones in accordance with the requirements of the Off -Street Parking Chapter. (TMC 18.56.020 Chapter Application) The Chapter includes a table that lists the required number of parking spaces for automobiles and bicycles. The Minimum Number of Off -street Parking Spaces Table is shown on Figure 18 -7 of the TMC. The table provides specific parking requirements for a number of common land uses. For example, fast food restaurants are required to have one parking stall for every 50 square feet of usable floor area and retail requires 2.5 stalls for every 1,000 square feet of usable floor area. The minimum number of parking stalls must be maintained over the life of the use. Any additional uses, either secondary or accessory in nature, must have parking available that does not impact the minimum parking of the original or primary use. (TMC 18.56.050 Required Number of Parking Spaces) Staff Report L13 -031 Page 6 of 12 102 1. Parking for a Use Not Specified The Director's Determination shall be based upon the requirements for the most comparable uses specified in the Off - Street Parking Chapter. Comparable Uses The most comparable use for a Live Work unit is a mixed use residential unit, which has a parking requirement of one stall for every dwelling unit. The applicant surveyed the adjacent Cities of Renton and Seattle and found that their respective standard is one stall or less. The applicant submitted a Traffic Impact Analysis (Parametrix, November 2012) that references the Institute of Traffic Engineers (ITE) Parking Generation Manual, 4th Edition. The Analysis shows less than one stall per unit for the peak parking period for the residential use. 2. Complimentary Use The Director may use his/her discretion in deciding whether to grant a 10% allowance for complementary uses. This project clearly will have a dominant use, which is residential with a total of 403 residential units. The remaining floor area will be generally 15,000 gross square feet of commercial space, a 10,000 square foot library, and 15,000 square feet of office space. This area of the City is encouraged to develop with a mix of uses. The types of uses are such that there is an expectation that site users will use more than one "business" while on the site. For example, on office worker will get lunch at a restaurant, a resident will visit the library, a customer will go to more than one store. 3. Shared Parking The Director may use his/her discretion in deciding whether to grant approval for shared use of parking. The proposal for the project is for the proposed six lots (A, B, C, D, E and the Library Parcel) to share the parking available throughout the five lots (A, B, C, D and E.) No criteria exist for the decision maker other than an assumption that the ability to share remains and works for the life of the project. Assurance can be given via reciprocal easements over the five lots for the users of the six lots. The City of Tukwila owns the property that will be sold to Tukwila Village Associates, LLC and to the KCLS. The Project has been envisioned as a mixed use project that functions as a whole. There are many references both within the DDA and the Development Agreement to sharing driveways, parking and other amenities and accessory uses in order to obtain a high - quality, pedestrian oriented development. Staff Report L13 -031 Page 7 of 12 103 Comprehensive Plan Policy A related policy from the Comprehensive Plan: 1.8.8 Encourage facilities and improvements that support transit use in new development, redevelopment, and street projects. The Tukwila City Council made the following findings during their deliberations on the Tukwila Village Development proposal. Within the Development Agreement is the following: 1. "Goal 8.2.22 of the City s Comprehensive Plan provides for the establishment of an overlay district in the designated urban renewal area generally between South 140th Street, 42nd Avenue South, South 146th Street, and 37th Avenue South that may allow increased building heights, reduced residential parking requirements, and other alternative development standards subject to specific criteria, in order to encourage well designed compact transit oriented and pedestrian friendly redevelopment to activate the community along Tukwila International Boulevard." 2. "The adoption of supplemental development standards and criteria providing for taller building heights and reduced parking requirements was intended to make urban densities and amenities more likely while the impact upon residential areas resulting therefrom would be lessened by requiring development along Tukwila International Boulevard, more significant structured parking and pedestrian friendly amenities;" Engineering Analysis Within the Traffic Impact Analysis prepared by Parametrix (May 2013,) (Attachment D) is a description (pages 14 -16) on peak parking demand. The author cites the Institute of Traffic Engineers (ITC) Parking Generation Manual. The analysis does not consider the phasing of the uses but instead considers the uses in total. The peak parking demand analysis (Table 9) is not absolutely relevant because the parking supply is not completely shared. All the parking for the residential units is within the garage spaces, which are not accessible to the commercial use customers; however, excess stalls are available for employees in some of the secured garage areas. This employee parking, when not in use by the employees during the evening and on weekends, will be available for "overflow" parking demand. Among the other uses — retail space, library, office and community policing — the estimated peak parking period would be noon during a weekday. The authors did not consider weekend parking demand. The higher amount of office space relative to the commercial space, which has a peak parking demand during the week mid- morning, relative to the commercial, which has a peak during mid- day, provides a greater opportunity for sharing to occur because of the difference in the peak demand periods. Of note, the Parametrix report states that although they did not analyze internal capture rates between the uses that they typically estimate a 10% internal capture rate. That means that 10% of the parkers on site typically will use more than one use without using their car for another trip. Staff Report L13 -031 Page 8 of 12 104 Phasing Plan and Parking Supply Because this is a large project that will be built over two — three years, (Attachment E) staff considered the implications of parking demand and supply during the phasing period. Attachment F shows that parking supply requirements, per the Zoning Code, are not evenly distributed between the five lots — hence the need for a shared parking decision. The applicant respond with the following solutions. (Attachment G) Phase 1 has the largest deficit of spaces. The Phase 1 - 73 stall deficit - becomes reduced by a 30 stall surplus produced by Phase 2 completion on the south side of S. 144 Street. Phase 3 completion brings the project into compliance and creates a 2 stall surplus. To mitigate the temporary Code shortage, the applicant discusses the construction of 18 on -street parking stalls in S. 144in Street, which is to be completed as part of Phase 1; their proposal to have temporary parking on proposed Lot B that would be available upon Phase 1 completion (Attachment H;) and the seven month absorption period for Phase 1 residential units and 17 month absorption for all the commercial space in Building A. The currently proposed completion of Phase 2 is within five months of the completion of Phase 1 and Phase 3 is within 12 months. It is not until all three phases are built that the project will meet the requirements of the Parking Code. In the end, at full build -out, the project meets the Code requirements for parking supply. Per the DDA, the City as property owner, must approve a phasing plan for development and can consider any parking issues related in the long term to a phase plan of development. (See Section 2.4 of the DDA Phasing; Development Parcels) Parking Supply Alternatives Transportation options Two Metro Bus Routes provide immediate access to the site. Route 128 stops on S. 144 Street and travels approximately every 15 minutes between West Seattle and Southcenter and serves the Light Rail station. Route 124 stops on Tukwila International Blvd (TIB) and travels approximately every 15 minutes during peak periods between the Light Rail station at Southcenter Boulevard and downtown Seattle. The intention of the requirement for a Transportation Demand Management Plan (discussed below) is to assist site residents and users in taking these transportation alternatives. Transportation Demand Management The project is within the Urban Renewal Overlay District and the developer has chosen to utilize the standards of the overlay zone. Those standards come with a requirement to submit a Transportation Management Plan, with is a transportation demand management tool. The Code says, "The property owner /manager shall prepare a Transportation Management Plan (TMP) to encourage alternatives to automobile use, and that provides each residential and commercial tenant with materials that may range from offering information about transit and Staff Report L13 -031 Page 9 of 12 105 bicycle options to providing transit tickets and passes." (TMC 18.43.070 Specific Urban Renewal Overlay Development Standards and Criteria) The City routinely administers TMPs through its Commute Trip Reduction Program, which is a program focused on sites with 100 or more employees. It is unlikely that this project will have an employer who is an "affected employer;" however, the CTR program could provide a framework for guiding and administering the transportation management plan for the site. Conclusions 1. Parking Standard for Live/Work Parking supply is per the City standards for all the residential units except the live work, for which there is no standard. The parking standard of one stall per Live/Work unit is comparable or exceeds the standard of adjacent jurisdictions and is consistent with the national standard per the ITE manual. 2. Complimentary Parking This large scale mixed use development is an exemplary project for demonstrated the potential to reduce vehicular trips. The ability to walk between multiple businesses or from home to business is the purpose of complimentary allowances. The design guidelines and standards for the area are created to encourage pedestrians to walk between buildings and uses and not to view the properties and their uses as isolated stand -alone fixtures in the neighborhood. Approval for the 10% complementary parking reduction is appropriate given the range of uses on the site, the differing peak parking demand periods as discussed in the Transportation Analysis and the potential for the internal capture of trips on the site. In addition, on -street parking will be available on the western half of the S. 144 Street block as part of Phase 1 street improvement. On street parking is currently available around the corner on 42 Avenue S. The parking on 42 Avenue S. however is not visible or obvious to visitors who are not familiar with the neighborhood. Surface lots across TM that serve commercial business will be obvious, which may result in some unsanctioned off -site parking. 3. Shared Parking Staff has reviewed the parking by phases and determined that when the development is complete, the project will meet the Zoning Code requirements for parking per the decisions above. Parking demand for special events could create a greater demand than supply. King County Library System (KCLS,) and the nonprofit organized to market and schedule the community space events, are users who will potentially have events that generate higher demand than currently considered. They will need to be involved in an association that coordinates the parking demand for all the site users. Staff Report L13 -031 Page 10 of 12 106 Users should be allowed access to all surface parking in order to maximize the site's flexibility to meet the variable needs throughout the day or a week. Sharing of some of the secure parking may also need to occur to balance the parking needs /demands across all five parcels or to provide overflow parking during special events. In order to manage the needs, the Transportation Management Plan will be a useful tool, and the administrator of that Plan, will play an important role in parking for the site. Circling and extra exiting/entering movements on City streets could occur if the parking is full on either the north or south side of S. 144 Street. Informational signage for parking could assist with this way finding need. In order to assure shared parking is available in perpetuity, reciprocal access and parking easements will be recorded against the five proposed lots. Staff's analysis of the phasing plan shows that a deficit of parking may occur depending on the absorption of the newly built space. The applicant also anticipates this parking variability by phase and shows an option for temporary parking on proposed Parcel B is developing on- street parking within the S 144 Street right of way and identifies the possibility of approaching surrounding property owners, such as the KCLS or the Tukwila School District, for use of their off -site parking when available. The deficit of parking stalls due to the phasing of the development shall be addressed by the Development Phasing Plan approved per the Disposition and Development Agreement. Any temporary parking approved as part of the phasing plan shall be required to obtain all applicable permits; comply with surface and storm water management requirement; and address maintenance and performance measures. Recommendation 1. Approve the application for a parking standard for the live /work units of one space per unit; 2. Approve a 10% complementary use allowance; 3. Approve shared parking across proposed parcels A, B, C, D and E subject to the following conditions: Prior to issuance of the construction permits for Phase 1, the applicant shall: a) Modify Boundary Line Adjustment/Lot Consolidation application (Land Use File # L13 -021) to include reciprocal parking access and maintenance easements across all lots. b) Adhere to the relevant procedures of the City's Commute Trip Reduction Program (Tukwila Municipal Code 9.44,) in order to implement the required Transportation Management Plan. The Tukwila Village Development Associates, LLC and its successor, shall perform the role of Employee Transportation Coordinator (ETC) Staff Report L13 -031 Page 11 of 12 107 and perform that role for all businesses on the Tukwila Village site. This role shall include providing information and incentives for alternatives modes of transportation such as transit, carpool etc. Annual reports of the efforts and results shall be provided to the city's CTR coordinator.

The annual growth from 2006 has varied year to year as is seen in Table 2 below. Additionally, a forecast of the average daily traffic (ADT) for the project horizon year of 2016 was used to help develop an assumed annual growth rate. Table 2.

Ll -o" The external trip generation summarized above contains vehicle trips of two types: pass -by trips and new trips. Pass -by trips are trips to /from sites where the vehicle was already on the street and as it is passing by the site, the driver turns into the site to make a stop before resuming their original trip. New trips are the remaining trips, where the primary purpose of the vehicle trip was to travel to and from the site. Only the 17,000 SF of retail uses are expected to attract pass -by trips. The pass -by trip reductions applied to the retails uses were as follows: • 65 percent for the PM peak hour (based on the regression equation found for Shopping Center in the ITE Trip Generation Handbook), • 55 percent for daily (although no data exists, it has been assumed to be somewhat less than during the peak hours), and • 65 percent for the AM peak hour (although no data exists, it has been assumed to mirror the PM peak hour trend). The regression equation was used rather than the average pass -by percentage because the pass -by data for shopping centers indicate that the pass -by rate exponentially increases as the square footage of the retail decreases. This presumably occurs because larger shopping centers are more of a regional destination rather than a local neighborhood center, where someone might drop by on the way home in the evening or to the office in the morning (i.e., a pass -by trip). The result of applying the above pass -by rates to the external trip generation for the retail uses is summarized in Table 6 below.

Trip Distribution and Assignment Based on the land use patterns in the general vicinity of the project, knowledge of the local transportation system, professional engineering judgment, and traffic counts along Tukwila International Boulevard, distribution and assignment of the project trips were estimated. The new project trip distribution is shown on Figure 4. New trips are estimated to travel to /from the site in the following pattern: • 25 percent to /from the north on TIB towards Seattle. • 25 percent to /from the west on S 144th Street towards nearby neighborhoods and Military Road S. • 25 percent to /from the east on S 144th Street towards nearby neighborhoods. • 25 percent to /from the south on TIB towards the City of SeaTac and State Route 518. Pass -by traffic to /from Tukwila Village is shown on Figure 5 and was assigned based on where the uses were located on the site as well as the volume being carried in the future baseline 2016 traffic streams on TIB and S 144th Street, which indicated the following distribution for the Phase 1 pass -by trips, which are likely to arrive from both TIB and S 144th Street: • 43 percent from southbound TIB Tukwila Village Development Associates LP 554 -6892 -001 Traffic Impact Analysis 10 November 12, 2012 122 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) • 26 percent from northbound TIB • 17 percent from westbound S 144th Street • 14 percent from eastbound S 144th Street For Phase 2 pass -by trips, the uses are set -back from TIB and much more likely to draw traffic only from S 144th Street. Given that, the Phase 2 pass -by traffic was distributed as follows: • 54 percent from westbound S 144th Street • 46 percent from eastbound S 144th Street Lastly, because the project site provides non - motorized system improvements in project vicinity, crosswalk volumes were projected to increase by 50 pedestrians per hour with the completion of the project. For comparison, 50 pedestrians per hour represents the difference between the values suggested for assuming the number of pedestrians per hour in a rural area (zero pedestrians per hour) and a suburban area (50 pedestrians per hour).

The proposed site uses were matched as close as possible to the data available. The parking demand estimates were compared to the • proposed parking supply. A total of 431 parking stalls would be provided on -site of which 293 would be in- building (garages) and 138 spaces would be surface parking stalls. Additionally, 23 on -street parking spaces would also be provided. Table 8 below summarizes the anticipated parking demand for a typical weekday. Table 8.

Therefore, the assumed daily distribution for family apartment units was used. 3 For the retail uses, the daily distribution of parking demand for Shopping Center (ITE Land Use 820) for a non - Friday, non - December weekday was used. To account for live -in tenants at the live /work spaces, 9 percent of the peak parking demand was assumed, which amounts to 6 parking spaces and is equivalent to an increase of 4 apartment units generating additional overnight parking demand from 10:00 PM to 7:00 AM. 4 Used data for Library (ITE Land Use 590). 5 Used data for Medical - Dental Office Building (ITE Land Use 720). 6 Used data for Government Office Building (ITE Land Use 730), which provides data for the time period from 9:00 AM to 4:00 PM. That was supplemented with data from Office Building (ITE Land Use 701) for the hours from 7:00 AM to 9:00 AM and 4:00 PM to 7:00 PM. Tukwila Village Development Associates LP 554- 6892 -001 Traffic Impact Analysis 16 November 12, 2012 128 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) Note that the above parking demand estimates have not been adjusted for the mixed -use nature of the site and the internal capture between uses, which would reduce the peak parking demand. The daily trip generation would experience a trip generation reduction of 10 percent due to internal capture and a similar reduction would likely occur for the peak parking demand. One other factor that may reduce the overall parking demand is the close proximity to King County Metro bus stops on Tukwila International Boulevard and S 144`h Street in the site vicinity (sf.e the Transportation System Conditions section for detailed information about the routes and stop locations). With the overall site peak parking demand peaking at 281 parking spaces, and 431 on -site parking spaces being provided, the proposed parking supply would be adequate.

Crash History The five -year history of vehicle crashes in the project vicinity was reviewed to see if the crash rate appeared to be unusually high. None of the locations studied experienced crash rates in excess of 1.0 crash per million entering vehicle. In other words, the crash rates were less than one in million. Additionally, no crashes were severe enough to cause fatalities. Table 11 summarizes the five -year crash history.

The quality of traffic operations at intersections was ranked with a level of service (LOS) on an alphabetic scale from LOS A to LOS F, with LOS A being the best operations and LOS F being the worst operations. This is consistent with the Highway Capacity Manual published by the Transportation Research Board. The deterministic software, Synchro version 7 (Build 773, Revision 8), developed by Trafficware, was used to study the intersection operations. Using the intersection traffic volumes shown on Figures 2, 3, and 6, the LOS results were obtained and are summarized in Table 13 below. Table 13. Intersection Level of Service Conditions Intersection Tukwila International Boulevard at S 144th Street S 144'" Street at 41st Avenue S /East Drive Northbound Approach Southbound Approach Existing 2012 Future 2016 Baseline Future 2016 with Prolecf LOS Delay ' LOS Delay LOS Delay C 35.0 D 36.1 D 38.9 B 13.1 B B 12.1 B 13.3 C 23.5 13.2 C 23.9 Tukwila International Boulevard at at North Drive (Westbound Approach) Tukwila International Boulevard at at Main Drive (Westbound Approach) S 144'" Street at South Drive (Northbound Approach) A 8.9 A 9.0 C 19.4 None of the intersections operate worse than LOS D. With Tukwila Village, the intersection LOS would degrade from LOS B to LOS C, however, LOS C is still an acceptable LOS. As identified in the City of Tukwila Comprehensive Plan, the LOS standard is LOS D in residential areas and LOS E in commercial areas. Therefore, all of the study intersections would meet the LOS standard and no specific mitigation is recommended to improve the LOS condition at the study intersections. Driveway Channelization The proposed driveways operate at acceptable LOS with the channelization shown on'the site plan. The Tukwila Infrastructure Design and Construction Standards do not contain specific channelization guidelines to follow for evaluating channelization proposed at driveways beyond LOS conditions, but do mention the City recognizes and uses the most current edition of A Policy on Geometric Design of Highways and Streets by the American Association of State Highway and Transportation Officials (AASHTO) for channelization guidelines. AASHTO does not have quantitative guidelines for recommending right -turn channelization and the City's standards indicate that the City recognizes the WSDOT Design Manual as a reference, which does have quantitative guidelines for right -turn channelization, therefore, that has been used to supplement the AASHTO reference. The greatest potential need for left -turn channelization on a public street to serve movements into the project site would occur at the S 144th Street/East Drive/41 st Avenue S intersection. In reviewing the AASHTO guidelines and extrapolating for a 30 -mph operating speed, the combination of left -turn volumes, advancing and opposing volumes at the East Drive intersection do not warrant the a left -turn lane. The greatest potential need for right -turn channelization on a public street to serve movements into the project would occur at the TIB/Main Drive intersection. At this intersection, 62 vehicles would turn into the Main Drive with 526 vehicles traveling advancing northbound behind them. However, there are two northbound travel lanes Tukwila Village Development Associates LP 554 -6892 -001 Traffic Impact Analysis 19 November 12, 2012 131 TRAFFIC IMPACT ANALYSIS - TECHNICAL MEMORANDUM (CONTINUED) and the posted speed limit is 40 mph there. The WSDOT Design Manual only recommends using the Design Manual Exhibit 1310 -19 in developing recommendations for right -turn lanes when multilane facilities have posted speed limits of 45 mph or greater. Additionally, given that King County Metro has a bus pull -out in close proximity that would conflict with a right -turn lane, no right -turn lane is recommended on TIB at the Main Drive. Driveway Sight Distances The sight distance exhibits prepared by Barghausen Consulting Engineers indicate that the proposed driveway locations would have adequate sight distance per City standards. Therefore, no sight distance improvements are recommended. It is recommended that sight distance triangles be regularly maintained. Driveway Access Spacing & Corner Clearances The proposed driveways were located based on site constraints and access spacing and corner clearance requirements. Note: The East Drive/41st Avenue S was not checked because it exists in that location today. Table 14 summarizes the distances between intersection corners and accesses. Table 14. Access Spacing and Corner Clearance Access North Drive Main Drive South Drive Corner Clearance 530 feet edge to edge from TIB (560 feet centerline to driveway center) 70 feet edge to edge from S 142nd Street (110 feet centerline to driveway center) 230 feet edge to edge from S 144th Street (260 feet centerline to driveway center) 140 feet edge to edge from TIB (195 feet centerline to driveway center) Access Spacing 270 feet edge to edge from Main Drive 270 feet edge to edge from North Drive 180 feet edge to edge from East Drive /41st Avenue S MITIGATION FEE REQUIREMENTS Mitigation fees are due to the City at the time of building permit issuance to pay for the project's proportionate share of impacts. Additionally, the proposed development must pass the concurrency test conducted by the City of Tukwila. CONCLUSIONS & RECOMMENDATIONS The proposed Tukwila Village would not create significant adverse impact on the transportation system. The primary recommendations are: • Maintain clear sight triangles • Pay for the project's proportionate share impacts via the City's traffic impact fee program Tukwila Village Development Associates LP 554- 6892 -001 Traffic Impact Analysis 20 November 12, 2012 132 TUKWILA VILLAGE Revised PHASED DEVELOPMENT PLAN 10/04/2013 PROPOSED PHASED DEVELOPMENT SCHEDULE PHASE PHASE 1: PHASE 2: PHASE 3: Milestone Target Date Design Review Application Submittal 06/01/2013 Design Review Approval 10/31/2013 Grading & Foundation Permit Application Submittal 11/01/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 11/01/2013 Building Permit Application Submittal 12/01/2013 Grading & Foundation Permit Issuance 02/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 02/01/2014 Commence Grading, Foundation & Engineering Work 02/15/2014 Building Permit Issuance 04/01/2014 Commence Building Construction 05/01/2014 Construction Completion / Issuance of Certificate of Occupancy 04/30/2015 Design Review Application Submittal 11/01/2013 Design Review Approval 01/31/2014 Grading & Foundation Permit Application Submittal 02/01/2014 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 02/01/2014 Building Permit Application Submittal 03/01/2014 Grading & Foundation Permit Issuance 05/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 05/01/2014 Commence Grading, Foundation & Engineering Work 05/15/2014 Building Permit Issuance 07/01/2014 Commence Building Construction 08/01/2014 Construction Completion / Issuance of Certificate of Occupancy 09/30/2015 Grading & Foundation Permit Application Submittal 11/01/2013 Engineering Permit Application Submittal (Utilities & Frontage Improvements) 11/01/2013 Grading & Foundation Permit Issuance 02/01/2014 Engineering Permit Issuance (Utilities & Frontage Improvements) 02/01/2014 Commence Grading, Foundation & Engineering Work 02/15/2014 Design Review Application Submittal 07/01/2014 Design Review Approval 09/30/2014 Building Permit Application Submittal 12/01/2014 Building Permit Issuance 04/01/2015 Commence Building Construction 05/01/2015 Construction Completion / Issuance of Certificate of Occupancy 04/30/2016 .4rrpeiradu-e 133
